The invention pertains to a process for manufacturing a cyclic urea adduct of an ethyleneamine compound, the ethyleneamine compound having a linear -NH-CH2-CH2-NH- group, the process comprising the steps of - in an absorption step contacting a liquid medium comprising an ethyleneamine compound having a linear -NH-CH2-CH2-NH- group with a CO2-containing gas stream at a pressure of 1 -20 bara, resulting in the formation of a liquid medium into which CO2 has been absorbed, - bringing the liquid medium to cyclic urea formation conditions, and in an urea formation step forming cyclic urea adduct of the ethyleneamine compound, urea formation conditions including a temperature of at least 120°C, wherein the total pressure at the end of the urea formation step is at most 20 bara, wherein the temperature in the absorption step is lower than the temperature in the urea formation step. It has been found that the process according to the invention makes it possible to obtain cyclic urea adducts in an efficient manner in the absence of metal-containing catalysts and to perform the process under relatively mild conditions, in particular relatively low pressure. More specifically, by separating the CO2 absorption step from the urea formation step, the CO2 absorption step can be carried out at relatively low temperatures and pressures. And because the CO2 is already present in the system at the beginning of the urea formation step, the pressure in the urea formation step does not need to be high.

A method of making a pyranine monomer composition comprises the step of reacting pyranine with a functionalizing agent that functionalizes the pyranine molecule with a polymerizable functional group to provide a composition of functionalized pyranine monomers, said functionalization reaction taking place in an aqueous reaction medium, and in the presence of a molar excess of said functionalizing agent, such that the functionalization reaction product is a monomer composition substantially free of unfunctionalized pyranine compound. The pyranine monomer compositions made by the method can be used to make fluorescent tagged water soluble polymer compositions that advantageously are substantially free of unpolymerized pyranine. The fluorescent tagged water soluble polymer compositions can be used in a method of inhibiting scale in industrial water systems.
